Xtreme Li-po Battery 3.7v 150 mah 15C (for nCPx ,nCPs , MSR X )

by Doug Andersen

Battery is good...amybe a bit heavy for the MCX...make SURE to not install battery all the way into holder, if you do it will cause the servo geras to bind and you will not be able to control your heli...just pull it back about 1 mm or so.
